Hello Everypony!
We all know that the people who design the plastic pony figurines always mess the manes up. I have some tips on how to fix that.
All mane styles start out with a dip in boiling water. Then, to make the ponies look like they do in the cartoon, follow one or more of these steps.
-To curl: Wrap the mane around a pen. (Rarity, Fluttershy, Pinkie Pie)
-To straighten: Fold a napkin in half over mane, press down. (Applejack, Twilight)
-To crimp: Put a series of bobby pins down mane, try to keep it straight. (Looks great for Rainbow Dash)
Let all mane styles dry (preferably overnight) and use a tiny bit of hairspray.
Trim as needed.
The hair style should stay for a long time.
